flat tire NISSAN SENTRA 2021 User Guide

11.ECO Mode
• The ECO mode helps to enhance the fuel economy by controlling the en-
gine and Continuously Variable Trans-
mission (if so equipped) operation au-
tomatically to avoid rapid
acceleration. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, refer to “En-
gine oil and oil filter recommendations” in
the “Technical and consumer informa-
tion” section of this manual.

DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires. Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. For additional
information, refer to “Tire chains” in the
“Do-it-yourself ” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-move ice and snow from the windows
and wiper blades.
• A sturdy, flat board to be placed under the jack to give it firm support.
• A shovel to dig the vehicle out of snow- drif ts.
• Extra washer fluid to refill the windshield- washer fluid reservoir.
DRIVING ON SNOW OR ICE

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It moni-
tors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit, and the “CHECK TIRE PRES” (ve-
hicles without a vehicle information dis-
play) also appears in the trip computer or
the “Tire Pressure Low - Add Air” (vehicles
with a vehicle information display) appears
in the vehicle information display, one or
more of your tires is significantly under-
inflated. If the vehicle is being driven with
low tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light. This system will activate only
when the vehicle is driven at speeds above
16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights
and audible reminders” in the “Instruments
and controls” section, and “Tire Pressure
Monitoring System (TPMS)” in the “Starting
and driving” sections of this manual.

CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road andaway from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Shif t the manual trans-
mission into R (Reverse), or the CVT into
P (Park).
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the ve- hicle and stand in a safe place, away
from traffic and clear of the vehicle.
6-4In case of emergency

If you have a flat tire, refer to “Flat tire” in

WARNING
• Improperly inflated tires can
fail suddenly and cause an
accident.
• The Gross Vehicle Weight Rat-
ing (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the Tire
and Loading Information label.
Do not load your vehicle be-
yond this capacity. Overload-
ing your vehicle may result in
reduced tire life, unsafe operat-
ing conditions due to prema-
ture tire failure, or unfavorable
handling characteristics and
could also lead to a serious ac-
cident. Loading beyond the
specified capacity may also re-
sult in failure of other vehicle
components. •
Before taking a long trip, or
whenever you heavily load
your vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Tire and Loading Information
label
1Seating capacity: The maximum num-
ber of occupants that can be seated in
the vehicle.
2Original tire size: The size of the tires
originally installed on the vehicle at the
factory.
3Cold tire pressure: Inflate the tires to
this pressure when the tires are cold.
Tires are considered COLD af ter the ve-
hicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km)
at moderate speeds. The recom- mended cold tire inflation is set by the
manufacturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to the ve-
hicle's GVWR.
4Tire size - refer to “Tire labeling” in this
section.
5Spare tire size.
6Vehicle load limit: Refer to “Vehicle load-
ing information” in the “Technical and
consumer information” section of this
manual.
Checking tire pressure
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge squarely onto the valve stem. Do not press too hard or
force the valve stem sideways, or air will
escape. If the hissing sound of air escap-
ing from the tire is heard while checking
the pressure, reposition the gauge to
eliminate this leakage.
3. Remove the gauge.

1. DOT: Abbreviation for the “Depart- ment Of Transportation”. The
symbol can be placed above, be-
low or to the lef t or right of the Tire
Identification Number.
2. Two-digit code: Manufacturer's identification mark. 3. Two-digit code: Tire size.
4. Three-digit code: Tire type code
(Optional).
5. Four numbers represent the week and year the tire was built.
For example, the numbers 3103
means the 31st week of 2003. If
these numbers are missing then
look on the other sidewall of the
tire.
O3Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate
the materials in the tire, which in-
clude steel, nylon, polyester and oth-
ers.

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km).
For additional information on tire replacing
procedures, refer to “Flat tire” in the “In case
of emergency” section of this manual.
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.Wheel nut tightening torque:
83 f t-lb (113 N·m)
The wheel nuts must be kept tightened
to specifications at all times. It is recom-
mended that wheel nuts be tightened to
specification at each tire rotation inter-
val.
WARNING
• Af ter rotating the tires, check and ad-
just the tire pressure.
• Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
• Do not include the spare tire in the
tire rotation.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.

1. Locate the statement “The com-bined weight of occupants and
cargo should never exceed XXX
lbs. or XXX kg” on your vehicle’s Tire
and Loading Information label.
2. Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX lbs. or XXX kg.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For ex-
ample, if the XXX amount equals
1,400 lbs. and there will be five 150
lbs. passengers in your vehicle,
the amount of available cargo
and luggage load capacity is 650
lbs. (1,400-750 (5 X 150) = 650 lbs.) or
(640-340 (5 X 70) = 300 kg.) 5. Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That weight
may not safely exceed the avail-
able cargo and luggage load ca-
pacity calculated in step 4.
Before driving a loaded vehicle, con-
firm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. For addi-
tional information, refer to “Measure-
ment of weights” in this section.
Also check tires for proper inflation
pressures. For additional informa-
tion, refer to “Tire and Loading Infor-
mation label” in this section.
LOADING TIPS
• The GVW must not exceed GVWR or GAWR as specified on the F.M.V.S.S./
C.M.V.S.S. certification label. • Do not load the front and rear axle
to the GAWR. Doing so will exceed
the GVWR.
